Combination boilers, or combi boilers, create condensation as a waste product. This condensation is taken away from the boiler through the condensate waste pipe or condensation pipe.
Extremely cold weather conditions can cause these pipes to freeze as the pipe usually leads from the boiler, through the wall to the outside of the building. Where the pipe meets the outside of the building is usually where it freezes.
How can I fix this issue?
If this happens you can easily fix this issue by thawing the frozen pipe with a hot water bottle or heat wrap that can be applied to the frozen area and allowed to defrost over time.
You can also pour warm water over the frozen part of the pipe can be more effective.
Once the pipe is thawed, you can reset your boiler and this should solve the issue.
Please take care if using hot water to thaw your condensation pipe – you should not use boiling water as this can be dangerous.
If your condensing pipe is above ground level, give us a call and well come to fix the issue.
